In amateur radio, a panadapter (short for panoramic adapter) is a device or software feature that provides a real-time, visual display of radio signals across a wide band
Converted remnants of an old 4.1 music system and added a mic to make a home PA system. Originally it was working on a 12V AC transformer. Interestingly
The ionosphere is a region of Earth’s upper atmosphere—extending from roughly 60 km to 1,000 km above the surface—where solar radiation strips electrons from atoms, creating a dense
In the world of radio frequency (RF) and electronics, transformers and baluns are close cousins. While all baluns are fundamentally a type of transformer, they serve distinct roles
A DDS VFO stands for Direct Digital Synthesis Variable Frequency Oscillator. It is an electronic system used in radio transceivers to generate a highly stable, adjustable radio frequency
I had installed it when the Sun was not that strong yesterday afternoon. So I decided to watch the pattern of working and changes in indicators as well
Earlier I had adjusted Si5351 calibration by editing the firmware and reuploading the corrected value after getting the correction value with reference to my FT-710 radio as frequency
After reading through the initial pages of the manual, I went ahead with installing the new MPPT Solar Charge Controller. Remaining pages were meant for setting up grid
